BleepingComputer.com: Detecting a floppy drive in windowsxp using xcopy

when I tried to use
C:\CSW>xcopy a:\nul ,
it is giving
Invalid drive specification
0 files copied.

Even
C:\CSW>xcopy c:\nul
doesnt work and give the same error.Please can you explain what the problem is. I will be so much greatful to you. My operating system is Windows XP SP2

Are you trying to copy all files in that directory? What exactly are you trying to do?

Here's some examples of uses for xcopy:

copy all files

xcopy *.* x:\dir

or a file

xcopy file.txt x:\dir

or a group of file with the same extension

xcopy *.txt x:\dir

or all files and subdirectories(except empty ones)

xcopy *.* x:\dir /s

or all files and subdirectories(including empty dirs)
xcopy *.* x:\dir /s /e

xcopy /? will give you more options.

yeah i know these thing..as i already explained i am trying to detect whether a floppy is present in present in the floppy drive or not

Good one...could you not do this?
dir a:\ >>c:\test.txt

yes we can when the floppy is present in the driver but we cant when it isnt because for dir it opens a gui based application saying that there isnt a floppy in the drive

yeah buddy got the answer..using dir is working..thanks..i checked it for copy and xcopy ..seems i forgot to check it for dir:D
